SemGroup provides the infrastructure to gather gas from the wellhead and move it to the marketplace. Located in key areas, our assets offer producers low and high pressure field services, processing and access to competitive markets.


We own and operate approximately 1,000 miles of gathering pipelines in Oklahoma and Texas, including the 50-mile Canton Pipeline that connects our processing facility in Northern Oklahoma to the STACK play in the central part of the state. Our four natural gas processing plants operate with a combined capacity of approximately 595 million cubic feet per day.
